What's new

LS engine grounding

glue lined heat shrink.
Yeah, they still end up leaking, It's really not an issue in my location. I just removed the orginal wire taps off of my trailer brakes on the axle from 1998. They were still working, I needed to drop the axle.
 
that doesnt matter.

ive seen them mounted some crazy places. where you want to mount them will be an oven so keep that in mind.

The ECU or the coils?

I want to mount the coils across the edge of the firewall where the red line is. ECU will be inside the tub on the back side of the firewall extension where the yellow square is. There's 15"-18" between where the ecu and the coils. I'm more concerned with interference from the coils messing with the ecu. I've been told it doesn't matter with GM ECU's.

ECU is mounted between driven and co driver on the back firewall, just below harness bar.

So the ECU and the coils are close to each other I take it?
